实验方法:用图1所示装置,根据ME法(数值评价法)来求PSE(主观等价点)。所采用的激励振动信号是以0.1、0.2、0.5、1、2、5秒六种时间长度的哈宁窗函数调制的具有80、85、90、95、100dB(VAL)五种量级,频率为40Hz的连续正弦波,和作为PSE比较基准的5秒时间长度的矩形波。将信号按5秒的时间间隔随机配置,记录在数字记录仪上,重现后进行评价实验。被检者为22～37岁的学生,男17名,女3名。采取坐势,
Experimental Method: The PSE (Subjective Equivalent Point) was obtained from the apparatus shown in FIG. 1 according to the ME method (numerical evaluation method). The excitation vibration signals used are five kinds of signals with five kinds of orders of magnitude of 80, 85, 90, 95 and 100 dB (VAL) which are modulated by the Hanning window function of six time lengths of 0.1, 0.2, 0.5, A continuous sine wave of 40 Hz, and a rectangular wave of 5 second time length as a base for PSE comparison. The signals are randomly placed at intervals of 5 seconds, recorded on a digital recorder, and reproduced for evaluation experiments. The subjects were 22 to 37-year-old students, 17 males and 3 females. Take sitter,
